Radiation shields are required in beamlines (BL) that transport synchrotron radiation (SR) to stop high energy radiation that is scattered by instruments upstream of a BL. Radiation shields guarantee radiation safety in the downstream of the BL and need to be installed in the vacuum system of the BL. In order to limit the opening against unnecessary scattered radiation and to keep the effective aperture for SR as large as possible, a new type of radiation shield, which utilizes tungsten alloy with an opening as an ultra-high vacuum chamber, has been developed.
